Lap-Belt Installation
• Figure A illustrates a rear-facing, lap-belt
installation.
• When not in use, always store the LATCH
connectors in the storage slots. See page 29.
1 Recline the child seat, then place it rear facing on
the vehicle seat. This child seat must be in the
recline position when installed rear-facing. See
Recline Adjustment on page 33.
2 Lift the cover and open the rear-facing lock-
off farthest from where the vehicle belt will be
buckled (Fig. B).
3 Pull the vehicle belt out, then pass it under the
LATCH bar and through the rear-facing belt slot
(Fig. C).
• The vehicle belt can be routed over or under
cover.
4 Route the vehicle belt across the child seat then
through the opposite rear-facing belt slot and
under the LATCH bar.
IMPORTANT: The vehicle belt must rest behind the
child seat buckle strap.
5 Verify that the vehicle belt is not twisted, position
the belt through the open lock-off, then buckle
(Fig. D).
6 Push the child seat firmly into the vehicle seat
while removing slack from the vehicle belt.
7 Tighten the belt, close the lock-off arm, and
replace the cover (Fig. E).
• The lock-off is properly closed when a click is
heard.
• To prevent damage, never extend the lock-off arm
beyond its normal open position and always keep
the lock-off closed when not in use.

• If your vehicle is equipped with an automatic
locking retractor (ALR), use of the lock-offs is not
required as long as the ALR is locked. Check
your vehicle owner's manual to determine the
type of retractor your vehicle has, and how to lock
the retractor.
WARNING! Do not use this seat
with a non-locking, two-point Emergency
Locking Retractor (ELR) vehicle belt.
the child seat is secure.
• The child seat is secure when it cannot be moved
more than 1 in. (2.5 cm) front-to-back or side-to-
side at the belt path. If the child seat is not secure,
repeat the installation process or use an alternate
seating location.
• When properly installed in the rear-facing position,
the back angle of the child seat should be 30º – 45º from vertical (not to
exceed 45º) when the car is parked on a level surface (Fig. F).
• If necessary, the proper recline angle can be achieved by placing a rolled
towel or pool noodle in the crease of the vehicle seat to level the child seat's
base.
WARNING! Do not raise the child seat off the front edge of
the vehicle seat. This could cause your child seat not to perform as
intended.
• Rear-facing installation can be improved by the use of the Versa-Tether. See
pages 29 – 32.
